Title: Power driven fluid circulating unit
IPC: F01D25/18
Filed: 1953-06-24
Abstract: 742,506. Lubricating. GARRETT CORPORATION. June 24, 1953 [Sept. 8, 1952], No. 17484/53. Class 12 (3). [Also in Group XXVI] A fan impeller 29 is driven by a turbine rotor 28, the shaft 27 being journalled in bearings 23, 24 which are carried by a support 17. The bearings are spaced by a tubular spacer 25 and a loading spring 26. Lubricant is conveyed to the surface of the shaft 27 by wicks 63 from an annular reservoir 15 which is packed with absorbent material (not shown) such as cotton. The lubricant is broken into a fine mist by the action of the rotating shaft and is drawn by fans 32, 40 through the bearings 23, 24. The mist is discharged by the fans 32, 40 through passages 59, 61 either through a filter blanket 64 to the reservoir 15 or back to the shaft 27. If the pressure of the driving air supply to the turbine exceeds a predetermined value, it opens a valve 71 against the action of a spring 72, and air then passes by way of an annular cavity 53 and ports 67 to passages 66 in the bearing support 17 to cool the bearings, and is exhausted by way of an annular cavity 56, passages 57 and ports 58 to the exterior.

Abstract: 704,898. Pressure cookers. PLATERS & STAMPERS, Ltd. July 24, 1951, No. 17489/51. Class 123(1) Relates to pressure cookers of the kind in which the pot 1 and cover 4 are secured together, with the interposition of an expansible gasket 7, Fig. 5, by the engagement of e.g. six spaced inwardly-turned lugs 6 on the cover with a like number of outwardly-turned lugs 3 on the pot. The lugs of, at least, some selected pairs of lugs, such as the four pairs adjacent the pot handle h, two on each side, have operative faces comprising spaced lands 8, 9 and 16, 17 separated by shallow recesses 10, 18, so that, upon rotation of the cover in the opening direction, a land 16 on one lug will be caused to engage the recess 10 on the other, Fig. 3, and prevent further rotation if a substantial pressure exists within the cooker. Further, one of the lugs adjacent the pot handle h, preferably a pot lug 3, is provided with a stop 14, deeper than the recess 10, and the cover lug 6 with a tail portion 20 to mate with a raised surface 21 on the pot, so that a part engagement of the cover and pot, Fig. 4, will merely cause the land 16 of the lug 6 to engage the stop 14 and prevent effective sealing of the cooker until all the lugs are fully engaged and the end of a lug 6 contacts a stop 15 on a lug 3.

Filed: 1928-06-18
Abstract: 319,296. British Celanese, Ltd., Mosley, D. H., Olpin, H. C., and Ellis, G. H. June 18, 1928. Nitro derivatives are obtained by nitrating arylsulphonyl derivatives of aromatic amines by means of aqueous nitric acid initially exceeding 55 per cent and not exceeding 75 per cent strength and, if desired, hydrolyzing the products. Substantially pure mono- and dinitro products are thus obtainable. In examples (1) 5- nitro-2-anisidine is made by nitrating p-toluene sulphon-o-anisidide with nitric acid 80‹ Tw. and hydrolyzing the product obtained with sulphuric acid; (2) 3:5-dinitro-o-anisidine is similarly prepared from p-toluene sulphon-o-anisidide, any mononitroamino compounds formed being removed by diazotization and filtration. In an analagous manner 3-nitro- and 3: 5-dinitro-4- toluidine are obtainable from p-toluenesulphonp-toluidide. Arylsulphonyl derivatives of aniline, p-anisidine, o- and p-phenetidine and o- and pchloraniline may be similarly nitrated and the products hydrolyzed.

Abstract: 1427584 Paper-making machines A AHLSTROM OSAKEYHTIO 13 April 1973 [21 April 1972] 17979/73 Heading D2A To form a non-woven fibrous web, for example of paper, a suspension of fibres is divided and passed through a plurality of parallel passages 5, 6 in which it is accelerated to emerge as jets in a common chamber 11 in which the jets are reunited, the suspension is then deflected approximately through 90‹ by surface 9, accelerated through constriction 8 and deflected again substantially through 90‹ by surface 10, and the suspension is passed through an outlet channel 12 of constant depth in which turbulence in the suspension is allowed to decay, the resulting web 13 then being deposited on the wire 1 of a machine for drainage. A transverse distributor 3 supplies the suspension to the passages 5 and is inclined to their axes to increase the inlet area of the passages 5 and thus reduce clogging. The suspension can be highly concentrated, e.g. 1-6% of fibres by weight. The passages 5 are cylindrical and lead into flattened passages 6 of reduced cross-sectional area which accelerate the suspension for delivery through outlets 7 into transverse chamber 11. In a modification (Fig. 3, not shown) the constriction 8 is defined by a spring plate (17) and is adjustable, the lower lip of the outlet channel is formed by a thin plate (19) and the cross-sectional area of the distributor 3 is also adjustable.
